Specicaton of Letters Patent. Patgntd ARH-o 26, 1921 Application filedJuly 22, 1916. Serial No. 110,760.

To all whom it may concern residing at 701 Villa in den lieben, Arbon Beit known that we, HEINRICH Marne, Switzerland, GUsTAv SCI-marries,residing at 40S Berglistrasse, rbon, Switzerland, and AnoLrBALrnNswniLnn, residing at Bahnhofstrasse L10, Arbon, Switzerland, haveinvented a new and useful Road-Sprinkler, of which the following is aspecification.

Our invention relates to improvements in road sprinklers in which thesprinkling width as well as the output can beregulated independently.

Reference is to be had to the accompanyinO' drawings in which:

Figure 1 is a longitudinal section oi the cylinder of the sprinkler andan elevation ci' the levers, etc., for regulating its sprinkling widthand output; Fig. 2 is a crosssection on line 2-2 of Fig. 1; Fig. `8 is alongitudinal section of the sprinkler cyl.- inder showing its valve inanother position than in Fig. 1, the controlling levers, etc., beingleft out; Fig. l is a section on line 4-4 of Fig. 3; Fig. 5 is anelevation illustrating an arrangement of regulating levers, etc., forcars where two men are in charge, and Fig. 6 is a section of adetail ofsaid lever arrangement.

Referring now to Figs. 1 to 4, 1 is the cylinder of the sprinkler towhich water is supplied through a pipe 2 at one end. rl`he cylinder 1the axis oi which extends lengthwise ot' the oar as customary has anumber of perforationg 3 over which moves a piston valve 5 having asector 6. rlfhe rod 15 of the piston valve is passed through a stuifingboX 37 in the cover 36 of cylinder 1. A washing-spray i is formed on theunderside of cylinder 1. l

Arranged in suitable bearings 39 1n front of the drivers seat is a shaft2O on which two levers 7 and 16 are free to me moved.

Lever 7 has a short arm 8 which is connected to a bell-crank lever 10,11 by means of a rod 9. The bell crank lever is pivoted in a suitablebearing 10. er rod 12 connects said bell-crank to a lever 41 made with asleeve 13 which is seated on the square end 14 of piston rod 15, theopening of the sleeve being of square cross section. 1t will be seenthat when lever 7 is moved, the pist0n rod and with itApiston 5 andsector 6 will be caused to turn.

by moving lever 16 the piston valve 5 is caused to slide in its cylinder1.

1n the position indicated in Fig. 1, the valve 5 and its sector 6 closeall the periorations 3. It, by moving lever 7, the valve 5 is turned inthe direction or" the arrow in Fig. 2, it will be seen that itsuccessively opens all the horizontal rows of periorations except theholes in the last ive vertical rows to the left in Fig. 1 which stillremain closed by piston 5. 1n order to open these, lever 16 is moved inthe direction of the arrow until piston 5 is at the left hand end ofitsl stroke, see Fig. 3.

It will be obvious that if the sector 6 is turned from the positionshown in Figs. 1 and 2, in which it closes all the rows ot perforations3, it'will first uncover only one horizontal row of perforations, sothat onli,7

a narrow width of the street or road will be sprinkled. As the sector isturned 'farther to uncover more horizontal rows oi perforations 3, thewidth of the vroad portion reached by the water discharged through theseperiorations will of course increase, until, with the sector in theposition shown in Fig. 4C the full sprinkling width is attained. n theother hand, if with the sector 6 turned to a fully or partly openposition, this sector, together with the valve 5, is moved lengthwise(without turning), it will be obvious that the sprinkling width willremain unaltered, but the total amount of water discharged, that is tosay, the output of the sprinkler, will be increased or diminishedaccording as such longitudinal movement causes the valve to uncover orcover additional vertical rows of perforations 3. It will bev seen thatin this manner the driver is enabled to regulate the sprinkler withincertain limits to any desired ratio of output and sprinkling width.

To open the washing spray 4 valve 5 is.

perforations 3 but opens the port of the washing spray.

When two men are in charge of the car, we prefer to so construct andarrange the controlling levers that they can be manipulated by either ofthem.

With this object in view, we make the shaft 20 so long that it extendsover the entire width of the car frame 2G. rlhe seat of the driver isindicated at 29, with the steering Wheel 36 in front of it, while theseat of the attendant is on the other side of the car, at 35. Thearrangement is such that the main output of both sprinkling cylinders isregulated by the same lever while the sprinkling width is regulated by aseparate lever for each cylinder. It follows that while the main outputwill always be equal for both cylinders the sprinkling width of eithercylinder may be regulated separately.

The lever 16 for regulating the output is arranged between the seats ofthe driver and his attendant so as to be Awithin easy reach of both men.

We furtherprovide two sleeves 22 and 23, which are keyed to, and a thirdsleeve 21 which is loose on, the shaft 20. Also keyed on shaft 2G is anarm 33, and a similar arm 34 is formed on sleeve 21. rlhese armscorrespond to the short arm 8 of lever 7 in Fig. 1 and each of them isconnected to the piston rod 15 of the valve 5 in one sprinklingcylinder 1. The connecting means be the same as those illustrated inFig. 1.

Each of the sleeves 22 and 23 is pr vided with a conical socket 45 and46, re. pectivcly, while sleeve 21 has two sockets 24 and 25.

@ne of these sockets, say 45, is illustrated on an enlarged scale inFig. 6. The sockets are adapted to receive one of two controlling levers27 or 28 which have tapered ends32 hitting into the sockets. A key 31 isprovided on the tapered end of either controlling lever, and acorresponding key-way 47 is formed in each of the sockets. A threadedring 30 may be screwed into the upper portion of each socket so as tohold the controlling lever in position.

ln Fig. 5, it is assumed that the driver is to manipulate all thecontrolling levers. Lever 27 is introduced into the socket 25 at hisleft, and lever 28 into theisocket 46, at his right hand side. By meansof lever 27, he regulates the sprinkling` width of one cylinder, and bylever 2S independently that of the other while by lever 16 he regulatesthe output of both cylinders simultaneously.. It will be seen that, inthe full lines position, lever 27 would be practically out of theattendants reach. Therefore, if the attendant is to manipulate thecontrolling levers, lever 27 is introduced into socket 24 at the rightand lever 28 into socket 45 at the left hand side of the attendant, asillustrated in dot 28 may also be introduced into sockets 24 and 46 soas to enable either the driver or the attendant to manipulate them. ltfollows that by this arrangement a variety of positions for thecontrolling levers is given of which the most suitable one may beselected under any conditions.

Preferably, we so construct the sockets and levers that the levers willface in the same direction always, even when transferred from one socketto another. llle are thus enabled to provide said levers withinscriptions such as Open, Shut, etc., on that side which is visible tothe men in any position of the levers.

Slice our invention enables the driver or attendant not only to slidethe valve 5, 6 in its cylinder 1 and to turn it as well but also toslide it without turning and vice versa not only the -ahsolute values ofoutput and sprinkling` widthV can be regulated but also their ratio; sothat it is` possible, for instance, to adapt the sprinkling width togiven conditionsbroad or narrow streets, etc.-thus increasing theusefulness of a car provided with the sprinkler.

if?. further advantage is that by the same aki al displacement of valve5 which controls the output the port 4 for the washing spray is alsocontrolled. As mentioned above, the washing spray can be operated onlyafter all the perforations 3 have been closed by valve 5 and sector 6,see F ig. 1.

lt will be observed that while the perforations 3 for the spray are atone side of the respective cylinders or sprinkler heads 1, the ports 4for the washing spray or jet A are located at the bottom of these headsor cylinders. We thus avoid the danger of having the spray from theperforations 3 sweep back to the cleaned portion of the street or road,the matter forced to one side by the jet from the port 4.

We claim:

1. ln a road sprinkler car, sprinkling heads or cylinders located ondifferent sides of the sprinkler car, independent means for controllingthe sprinkler heads on different sides, and operating levers for saidmeans, said levers being transferable from positions near thelongitudinal center of the sprinkler car to positions near the sidesthereof, to facilitate control of the sprinkling operation by anattendant stationed at either the left or the right of the car.
